Summary: Enables protein serine/threonine kinase activity and protein tyrosine kinase activity. Involved in several processes, including pexophagy; regulation of vesicle-mediated transport; and ribosome biogenesis. Located in several cellular components, including P-body; cellular bud tip; and spindle pole body. Part of monopolin complex. Used to study several diseases, including advanced sleep phase syndrome; brain disease; familial adenomatous polyposis; neurodegenerative disease (multiple); and syndromic X-linked intellectual disability Najm type. Human ortholog(s) of this gene implicated in advanced sleep phase syndrome 2 and invasive ductal carcinoma. Orthologous to several human genes including TPTEP2-CSNK1E (TPTEP2-CSNK1E readthrough); CSNK1D (casein kinase 1 delta); and CSNK1E (casein kinase 1 epsilon).

Pex3 confines pexophagy receptor activity of Atg36 to peroxisomes by regulating Hrr25-mediated phosphorylation and proteasomal degradation.
Title: Pex3 confines pexophagy receptor activity of Atg36 to peroxisomes by regulating Hrr25-mediated phosphorylation and proteasomal degradation.
P-bodies are required for the efficient completion of meiosis. P-bodies were found to be present during all phases of the meiotic program and to provide protection for the Hrr25/CK1 protein kinase, a key regulator of this developmental process.
Title: P-Body Localization of the Hrr25/Casein Kinase 1 Protein Kinase Is Required for the Completion of Meiosis.
The C-terminal region of Hrr25 is required for normal inhibition of expression of Haa1 target genes TPO2 and YRO2 and is important for cell growth but is not required for cell morphogenesis
Title: Casein Kinase I Isoform Hrr25 Is a Negative Regulator of Haa1 in the Weak Acid Stress Response Pathway in Saccharomyces cerevisiae.
Together, the Hrr25 central domain and Mam1 form a novel, contiguous embellishment to the Hrr25 kinase domain that affects Hrr25 conformational dynamics and enzyme kinetics.
Title: Structure of the Saccharomyces cerevisiae Hrr25:Mam1 monopolin subcomplex reveals a novel kinase regulator.
This recruitment requires Hrr25 kinase activity and the Dcp2 decapping enzyme, a core constituent of these RNP granules. Interestingly, the data indicate that this localization sequesters active Hrr25 away from the remainder of the cytoplasm and thereby shields this enzyme from the degradation machinery during these periods of stress.

Ypt1 binds and activates Hrr25 to spatially regulate its kinase activity.
